Because Justin Timberlake is one of three co-creators of the Memphis-style BBQ joint in New York's Upper East Side, he hung out at the "One Night Only" party hosted by Neuro that featured an exclusive performance by One Republic.
Justin and Jessica tried to act casual and play the whole "I'm friendly with my exes" card, but these two weren't exactly hiding their affection as Biel was practically sitting on JT's lap as they posed for a photo op with Elton John.
"They were cute together and seemed happy and natural. They stayed by each others' side the whole night," an onlooker tells Celebuzz.
Timberlake and Biel met in 2007, dated for nearly four years before announcing their split in a joint statement this past March.
The statement read: "Addressing the media speculation regarding Jessica Biel and Justin Timberlake's relationship, we are confirming that they mutually have decided to part ways. The two remain friends and continue to hold the highest level of love and respect for each other,' says the announcement.
I call B.S.
The couple started to rekindle their former flame over the July 4th weekend when Timberlake was seen "visiting" Biel in Toronto where she was working on a film. They were spotted riding bikes and getting brunch together. Two activities that are only done by couples or groups of single women who want to bitch about all the couples riding bikes and crowding their favorite brunch spots.
Then later that month, Biel cheered him on when JT played golf in the Shriner's Gold Tournament in August, sitting front row like a basketball wife.
Even though they've been low key seeing each other for the past few months, they've also been dating other people. Timberlake was linked with his "Friends With Benefits" co-star Mila Kunis, Olivia Wilde and even Scarlett Johansson, he basically gets all of Ryan Reynold's sloppy seconds.
And while Biel was casually meeting up with Timberlake she was also linked to Bradley Cooper and Gerard Butler.
It's only a matter of time before Biel is linked with Ryan Reynolds and then once Timberlake dates Blake Lively, Biel and Timberlake will have collectively swapped spit with every eligible single star in young Hollywood. These two would win 6 degrees of separation every time simply based on who they've slept with.
However, bike trips started becoming more serious when Biel was spotted last week at the after party for Justin's premiere for "In Time." She wasn't at the movie but was right there for the after party where onlookers said they were "attached at the hip."
"[They] became more and more affectionate, sneaking kisses, whispering to each other and sharing quick back rubs and caresses," says the onlooker, "At one point, she pretended to punch him a couple times and he gamely bounced up and down like a jack in the box."
Punching him like a jack in the box? A sure sign of affection.
